CONCENTRATOR AND AMALGAMATOR.

T 0 all whom it may concern.-

iBe it known that 1, ROBERT L. Rorsn, a cltizen of the United States,residing at- 'Martinsville, in the county of Morgan and State ofIndiana, have invented certain new and useful Improvements inConcentrators and Amalgamators, of which the following is aspecification.

This invention relates to amalgamators and concentrators, and one of theprincipal objects is to provide simple, reliable and efficient means forseparating the fine particles of valuable metals from muddy water andslime and which will thoroughly agitate and carry oil the tailings.

Another object of the invention is to provide an amalgamator of simpleconstruction comprising a casing provided with feed pipes for the waterat opposite ends thereof so that as the water meets in the center oi?the casing a vortex is created which thoroughly agitates the liquid,means being also provided for jarring the casing to release theparticles of metal from the muddy water and to permit them to settle atthe bottom, while the water is carried oii as tailings by a revolvingwheel provided with a series of buckets.

Still another obj eet of the invention is to provide a device of thecharacter described with a rotating wheel having a series of resilientspokes carrying buckets at their ends for discharging the tailings fromthe casing, means being provided for retarding the buckets to throw thecontents thereof out of the casing.

Another object of the invention is to provide an amalgamator in which avertex is created at the center of the bottom of the casing tothoroughly agitate the slime and liquid as it enters the apparatus andto pro vide suiiicient space above the vortex for a pool of still water,thus permitting the impalpable particles of the metal to be thrownupward violently into the pool, from which said particles will settle bythe jarring action of the apparatus down upon the inclined sides of theamalgamator casing which may be provided with a coat of mercury toarrest the particles.

Still another object of the invention is to provide a tappet mechanismfor jarring the casing during the operation of the apparatus to permitthe fine particles of metal to settle Specification of Letters Patent.

to the bottom and separate the said particles from the muddy water andslime.

These and other objects may be attained by means of the constructionillustrated in the accompanying drawing in which,

Figure 1 is a side elevation of an amalgamator and concentrator made inaccordance with my invention. Fig. 2 is a longitudinal section andpartial elevation of the same. Fig. 3 is a vertical sectional view takenon the line 3-3 of Fig? 2 looking in the direction indicated by thearrows. Fig. 4: is a vertical section taken on the line stt of Fig. 1looking in the direction iudicated'by the arrows.

Referring to the drawing for a more particular description of myinvention the numeral 1 designates a base upon which is secured a pairof track rails of suitable form. Rising from the base 1 is a pair ofstandards 3 connected to the base by suitable braces 4:. A pair ofuprights 5 rise from the base 1 near one end thereof and braces 6 securesaid uprights in place.

A carriage comprising side members 7 and end members 8 and 9 is providedwith track wheels 10 journaled upon axles 11 secured to the side members7 of the carriage. The wheels 10 are supported upon the tracks 2.

A suitable sheet metal casing which may be either sheet iron or copper,depending upon the use of the apparatus as a concentrator or anamalgamator, consists of a lower section 12 supported upon the carriageby means of suitable braces 13 connected to the side members 7 and tothe lower section 12 of the casing. As shown in Fig. 8 the member 12 ofthe casing is flared at its upper end and provided with spill-ways 1 1at the opposite sides thereof. Suitable metal feed pipes 15 lead intothe opposite side of the bottom of the casing member 12, as shown moreparticularly in Fig. 2 and at the upper end of said metal feed pipesflexible hose or similar pipes 16 are led to the source of supply of thewater or slime. At the bottom of the member 12 a slide clean-out door 17is provided. The removable or telescopic upper section 18 of the casingis provided at opposite ends with a suitable sliding catch 19 adapted toengage a keeper 20 connected to the upper edge of the lower section 12of the casing, as shown more particularly in Fig. 2. The member 18 formsa cover for the casing and is provided at opposite sides with a T-shapedslot comprising a vertical portion 21, which extends to the lower edgeof the member 18 and the horizontal cross slot 22.

Journaled in the standards 3 is a shaft 23, upon one end of which is apulley 24 adapted to receive a belt from a source of power. Secured tothe shaft 23 within the cover member 18 is ahub 24%. Secured to the hub2 1 is a series of spring spokes 25, said spokes having oppositelyextending base portions 26 secured to the hub 24* by suitable clamprings 27. Connected to the outer ends of the resilient spokes 25 is aseries of buckets 28. Extending throu h the top of the cover 18 is aneye bolt 29 adapted to be adjusted into the path of the buckets 28 asthey are rotated. An eye 30 in the bolt 29 is adapted for the connectionof the rope to lift the cover 18. Atone side of the cover member 18 is asliding door 31 adapted to cover an opening 32 in the member 18, andsliding in guides 31.

A spiral spring 33 is disposed between the front end 9 of the carriage 7and an upright 3% secured to the base 1. At the opposite end of thecarriage 7 a pair of run-ways 35 is hinged to the end 8 of the carriageby means of hinges 36. Veighted balls 37 are placed in the run-ways anda suitable buffer 38 is secured to the end 8 of the carriage in linewith each of the run-ways. Two connecting rods 39 each provided with ayoke 40 are pivotally connected one to each run-way, 35, said connectingrods 39 being pivotally mounted upon the cranked portions 41 of theshaft 42, said shaft being journaled in the uprights 5 and provided witha pulley 43 adapted to be connected to a source of power by means of asuitable belt.

The operation of my invention may be briefly described as follows: Thewater or slime containing the values is led through the feed pipes 15into the lower member of'the casing, said water being discharged atopposite points creating a vortex in the center thereof which thoroughlyagitates the liquid. As the buckets 28 are rotated, each bucket comesinto contact with the eye bolt 29 to throw the contents out through theopening 32, the tailings being led off through a sluice-way. As therace-ways 35 are raised and lowered alternately the weighted balls 37strike the buffers 38 and vibrate the casing against the stress of thespring 33, the latter returning the carriage and casing to its initialposition after each stroke. Owing to the horizontal slot 22 the casingcan move horizontally without interfering with the shaft 23.

7 My invention is easy to operate, is quick in action, is efficient forits purpose of thoroughly separating the small particles of the valuesfrom the muddy water and slime and is inexpensive to install andoperate.

Having thus fully described the invention what is claimed as new is:

1. In an apparatus of the character described, a casing mounted upon awheeled carriage, feed pipes leading into the bottom of the casing atopposite ends thereof, means for vibrating the casing, a telescopiccover for said casing provided with an opening, and a series of bucketswithin the cover, said buckets being mounted upon resilient spokesconnected to a shaft, means for rotating said shaft, and means forretarding the buckets to discharge their contents out through the coverof the casing.

2.
